  • Sea water reverse osmosis system to reduce concentrate volume prior to disposal
    Patent number: 10005681
    Abstract: The present invention includes systems and methods for treatment of seawater RO system for recovering most of the water (i.e., 85-90%) from the concentrate of a brackish groundwater reverse osmosis treatment system that may use, e.g., a batch method. With proper pH control and antiscalant dosage, the batch-treatment SWRO system of the present invention can be used to recover water from silica-saturated RO concentrate without fouling the membranes. Silica concentrations of over 1,000 mg/L are attainable with relatively minimal pre-treatment of the silica-saturated feed solution.
    Type: Grant
